It might be a good deal, but I have a better deal, so no thanks...
Yes. Because it is abundant.
Software is not abundant... Software gets constantly created at great cost.
Once created, software is abundant - I can create copy after copy after copy after copy at no additional cost and distribute it online at no additional cost to anyone who wants it, whenever they may want it. There is no scarcity. I cannot "run out" or "sell out" of digital software.
It's already extremely abundant
Abundant refers to something specific - it means that a good is no longer scarce. Air is not scare. Air is abundant, because there is more air than everyone human being currently on earth could feasibly consume, whenever they may want to consume it. (If you go to space or underwater, air ceases to be abundant).
Food is still scarce. Not every human currently on earth can eat as much food as they want, of whatever food they may want, whenever they may want. Even if food is
less scarce than it was historically, it is not
abundant.
A piece of software is much more like air than like food.
Money, and the market, is ultimately nothing but a mechanism to ration/allocate scarce goods efficiently. If a good is abundant, it does not need to be rationed. If it does not need to be rationed, the market serves no purpose. Why should society keep a mechanism in place that serves no purpose?
Now, in the case that some goods will always be scarce. The free market system is dependent on the fact that the vast majority, if not all, goods are scarce and that markets are the most efficient way to allocate all those goods. However, if the vast majority of goods are abundant, this ceases to be the case. If only a few goods are scarce, it is arguably more efficient for society to ration what isn't, than expend energy in maintaining free market institutions for those goods.
When the net energy expended in maintaining a market system is greater than the net energy expended in rationing scarce goods, it no longer makes sense to maintain a market system.
